Re: How is Hematite mined? - MadSci

2004-1-20 · Typically, hematite is mined by open pit mining. Overburden is removed, then the ore is mined from an ever-deepening hole. The mineral and rock is first stripped by blasting the rock with explosives and removing it with enormous trucks - with capacities over 150 tons. The ratio of mineral to rock can be quite large - up to 1.5 to 1 for hematite.
